How to remove unused addons lua settings

[gmarco]

Hi,
once there was the old curse client that have a function to delete the unused (not present anymore) addons setting *.lua and *.bak .
This very handy functionality was removed in the new Curse/Twitch client. I don't find in Minion either.

So I am here to ask if there is a program, a batch file, something that could do the job.

Thanks.
